The detailed description of specific embodiment preferred embodiment
A drawer sliding rail component of finishing according to a preferred embodiment of utility model is shown in Fig. 1 and Fig. 2, and it comprises:
This drawer sliding rail component further comprises the second c-shaped slide rail 20 of a section, and it has a shape and a size corresponding to first slide rail 10, so telescopically is sleeved on the inside of first slide rail 10.This second slide rail 20 has extension 22 and symmetrical with it lower extension 23 on one.Last extension 22 has one second groove 222, and it cooperates with first groove 122 and forms a long axis direction upper ball bearing runway.
This drawer sliding rail component further comprises two ball bearing assemblies 30, and as shown in Figure 3, each ball bearing assembly 30 comprises a plurality of ball bearings 40 and and is used as the flat, rectangular plastic strip 50 that ball bearing keeps seat.This plastic strip 50 comprises along its long axis direction asks every a plurality of perforation 51 that are used to accept ball bearing 40 that distribute, and a plurality of approximately equally spaced horizontal line of rabbet joint 52 of setting of its both sides that is positioned at.This line of rabbet joint 52 has a degree of depth and approximates 0.8 of these plastic strip 50 width.
As shown in Figure 1, the front end of the vertical wall 11 of this first slide rail 10 respectively near on extension 12 and lower extension 13 places be rushed out a pair of vertical plate 14a and 14b.The tail end of second slide rail 20 respectively on this extension 22 and lower extension 23 go out a pair of protuberance 24a and the 24b of stopping outward.When this ball bearing assembly is assembled between first slide rail 10 and second sliding 20 as shown in Figure 2, the ball bearing 40 of this ball bearing assembly can roll at the long axis direction of this first groove 122 and second groove, 222 these drawer sliding rail components of formed ball bearing runway upper edge, the plastic strip 50 of this ball bearing assembly laterally is limited between vertical wall 11 and the vertical component effect 124, so first slide rail 10 and second slide rail 20 are that mutual telescopically connects together slidably.Moreover, because this is to vertical plate 14a, 14b and this are to stopping protuberance 24a, the setting of 24b, when second slide rail 20 is pulled out first slide rail 10 toward the front end of first slide rail 10, two ends of plastic strip 50 will be the compressing of first slide rail 10 and second slide rail 20, and the while also stops to advance of second slide rail 20, as shown in Figure 4.Give the credit to a plurality of lines of rabbet joint 52 on the ball bearing assembly, along two when terminal of the long axis direction compressing plastic strip 50 of plastic strip 50, plastic strip 50 can produce translations (translation) distortion, and reaches a shock-absorbing effect at a slide rail 10 and second slide rail 20.
As shown in Figure 1, the vertical wall tail end of this first slide rail 10 has a catch 15 that can be bent up into standing upright, it is after second slide rail 20 and this two ball bearing assemblies 30 are installed in first slide rail, 10 inside, just bent up with vertical wall 11 and spent, so stop second slide rail 20 to deviate from first slide rail 10 from the tail end of first slide rail 10 into about 90.
